AUTQMATIG SHIP-STEERING MECNISM.

Application filed April 1 To all whom it may concern Be it known that citizen of Yugoslavia,

I, JUSTIN Flznsiin, a residing at Saugertres,

in the county of Ulster and State of New York, have invented certain 11 Improvements in Automatic Mechanism, of which the specification.

ew and useful Ship-Steering following is a This invention relates to operating mechanism for ships rudders and it has for one object to provide a simple form of power mechanism for operating a ships rudder.

A further object is to provide an indicating device located in the pilot house. for

showing the angular position of the rudder.

Another object relates to the provision of a hand operating means capable of operating through the same connecting elements as the power mechanism in the event of disabling of the latter.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel eatures of the more particularly set forth.

invention are Fig. 1 of the drawings is a plan view showing my improved steering mechanism applied to a ship.

Fig. 2 is a partial enlarged longitudinal vertical sectional view of the steerin mech anism, taken along Fig. 3 is showing particularly the the line 2-2-of a detail front elevational ylew,

drive mechanism.

Fig, 4 is a detail tikansverse vertical sec tion on the line 4-4 0 Fig. 2.

Fig. 5 is a plan view of one of the winding drums.

In Fig, 1 of the a ship in general drawings outline at laterally around pulleys 16 and then drums wardly to connect to These transverse shaft 18., shown vary in diameter an arm 12 I have indicated 10, the rudder 11, being adaptedvfor operafixed to the 13, which exstern, of the Connected to 15 extending for- 17 fixed on a drums 17 as from end to end and are formed with grooves 19 in which the ropes are localized. The object of this con struction is to compensate for tive movements of the two rop difierent rela-=' as as one pulls 8, 1922. serial No. 555,147.

stantly rotating shaft 27 (see Fig. 3) which may be driven in any suitable manner, the connections between the shafts 26 and 27 comprising the bevel gears 28 and 29 fixed on opposite ends of a vertical shaft 30 and engaging gears 31 and 32 on the shafts 26 and 27. v

The gears 25 may be individually rotatively engaged with the shaft 26 by means of a clutch sleeve 35 feathered on the shaft 26 and adapted to engage clutch faces 36 on the gears. The sleeve 35 is shifted by a lever arm 37 fixed on a rock-shaft 38 which extends rearwardly and is adapted to be manually rocked. As here shown a clutch element 39 is fixed on the rear end of the rock-shaft 38 and is engaged by one end of a double ended clutch sleeve 40 fixed on a -steersmans wheel e1 loose on shaft 38. Ad-

jacent the opposite end of the clutch sleeve 40 is a second clutch element 42 loose, but not axially movable onshaft 38, an expansion spring 43, coiled around shaft 38, normally holding the clutch sleeve 40 in en gagement with the clutch element 39. Fixed to clutch element 42 is a small sprocket wheel 44: connected by a chain 45 with a large sprocket wheel 46 on the shaft 23. As Wlll be apparent, if necessary the rudder can be operated by hand by pushing the wheel 41 forward until its clutch sleeve 40 engages with the clutch element 42.

I also referably provide an indicating device which shows the an lar positioning of the rudder 11, This device here comprises a pointer 50 adapted to swing across a scale 51 and being fixed on a stub shaft 52 on which is also fixed a large sprocket wheel 53 connected by a chain 54 with a small sprocket wheel 55 to which is co-axially fixed a bevel gear 56 meshing with a pinion 57 on a short vertical shaft 58 on which is a worm ear 59 engagin a worm pinion 60 fixed on s aft 23. It wil reducing gearing above described is proof course he understood that the portioned so as to cause the pointer 50 to swing in correspondence to the rudder 11. The wheel 41 and pointer 50 will be suitably positioned in the pilot house, indicated at 65, of the ship.

While I have illustrated and described a preferred embodiment of my invention it is to be understood that I do not limit myself to the precise construction here shown, and that various changes and modifications might be .made therein without departing from the spirit and scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. In combination with a rudder, a rotatable shaft operatively connected thereto, power mechanism for rotating said shaft in opposite directions, control means therefor including a clutch element, an arm adapted to shift said clutch element, a rock-shaft on which said arm is fixed, a pair of clutch elements one of which is fixed and one loose on said rock-shaft, a clutch sleeve loose on said shaft between said clutch elements, a steersmans wheel fixed on said clutch sleeve, and means forming an operative connection between said loose clutch element and said first mentioned shaft.

2. In combination with a rudder, a rotatable shaft operatively connected thereto, a power mechanism, for rotating said shaft in opposite directions, control means therefor including a clutch element, an arm adapted to shift said clutch element,'a rock-shaft on which said arm is fixed, a pair of clutch elements one of which is fixed and one loose on said rock-shaft, a clutch sleeve loose on said shaft between said clutch elements, a steerssignature.
